The HPS Silicone Heater Hose Kit is designed as a high-performance replacement for aging or damaged OEM heater coolant hoses. Made from 3-ply reinforced high-temperature silicone, these hoses offer exceptional durability and resistance to heat, ensuring reliable performance under prolonged exposure to under-hood and coolant temperatures up to 350°F.Each hose is precision-formed with factory-correct bends and curves, guaranteeing a direct-fit installation without modification. The included 100% stainless steel non-perforated embossed clamps provide a secure attachment without cutting into the silicone, ensuring leak-free operation over the long term.This kit effectively prevents coolant leaks, cracking, and collapsing hoses, addressing common issues found in standard rubber heater hoses. Race-proven and engineered for both performance and longevity, the HPS Silicone Heater Hose Kit delivers consistent, reliable service for daily driving or high-performance applications.Note: Silicone hoses have a higher water permeation rate than standard EPDM rubber hoses. Regular coolant level checks are recommended for vehicles used daily.
